Varicella-Zoster Virus by PCR
Also known as: VZVPCR
Use
The Varicella-Zoster Virus by PCR test is used to detect the presence of the varicella-zoster virus in various specimen types such as blood, cerebrospinal fluid (CSF), ocular fluid, tissue, or vesicle fluid. It is a qualitative test performed using the polymerase chain reaction (PCR) methodology which is particularly useful for detecting viral DNA in patients who present symptoms. This test helps in diagnosing infections like chickenpox or shingles caused by the varicella-zoster virus.
Special Instructions
Not provided.
Limitations
A negative result does not rule out the presence of PCR inhibitors in the patient specimen or assay-specific nucleic acid concentrations below the level of detection by the assay. This is a qualitative test; thus, it does not provide information on viral load. It is not FDA-cleared or approved, as it is a laboratory-developed test performed in a CLIA-certified laboratory for clinical purposes. The test's performance characteristics were determined by ARUP Laboratories.
